thermodynamically favored

Postby Michelle Chernyak 1J » Sun Feb 04, 2018 8:24 pm

When it says a reaction is thermodynamically favored, it is referring to just the enthalpy or the free energy?

just free energy

Thermodynamically favored means the reaction will proceed spontaneously, and it refers to deltaG, the free energy.

I think the reaction can proceed spontaneously even when delta H is positive, so maybe it just refers to free energy?

A reaction that is thermodynamically favored has a negative ΔG, so the products are at a lower energy than the reactants so that reaction will spontaneously occur. For ΔG to be negative, ΔH has to be small in the equation ΔG=ΔH−TΔS.

It refers to the free energy which must be negative in oder to be favored and because of this the entropy is positive and the process is spontaneous.

It refers to the gibbs free energy, which is partly dependent on enthalpy. In a sense, its both, but the specific criteria we use to determine whether a reaction is thermodynamically favored is gibbs free energy.
